Now the main question, Is there any way to restore that behavior to the Cinnamon desktop environment.

Any suggestions are appreciated.

The keyboard app lets you specify custom shortcuts so you could try that. There is no default for shutdown so you'll have to disable or change the logout shortcut, which is what ctrl+alt-del is mapped to.

Mint Donor #6036If your problem is fixed, please mark your thread as [SOLVED] by editing the title of the first message in the thread.

The Ctrl-Alt-Del shortcut is already in use for logout: Cinnamon Settings > Keyboard > Shortcuts tab > System (at the left). You'll probably need to unset that if you want to use a custom shortcut to gnome-session-quit --power-off with the same key combination.

You can unset it by selecting the Ctrl-Alt-Delete text and then pressing Backspace.
